Google Colab 无法访问云端硬盘内容

Question

即使我将我的 Google Drive（及其中的数据集）定义为 google colab，但是当我运行我的代码时，我给出了这个错误：FileNotFoundError: [Errno 2] No such file or directory: 'content/drive/My Drive/.. ..

我已经在 google colab 中定义了 google drive，我可以通过 google colab 访问它，但是当我运行我的代码时，我给出了这个错误

Answer 1

我认为你/在你的/content/drive...。

通常通过以下方式挂载您的云端硬盘文件

from google.colab import drive
drive.mount('/content/drive')

Answer 2

挂载后，进入数据集文件夹。

cd content/drive/My Drive/Convolutional_Neural_Networks/dataset/

不要使用！。然后将您的目录设置为./training_set
